20241030在荣品PRO-RK3566开发板的适配Rockchip原厂的buildroot的时候配置DTS中的电源域
2024/10/30 17:38
请问 RK3566开发板上的 电源配置 和 DTS文件是如何对应的？
底板原理图 PRO-RK3566-B-20210329+原理图.pdf
vccio4-supply 是1.8V。
对不上呀？
Z:\source\kernel\arch\arm64\boot\dts\rockchip\rk356x\pro-rk3566.dts
&pmu_io_domains {
status = "okay";
pmuio2-supply = <&vcc3v3_pmu>;
vccio1-supply = <&vccio_acodec>;
vccio3-supply = <&vccio_sd>;
vccio4-supply = <&vcc_3v3>;
vccio5-supply = <&vcc_3v3>;
vccio6-supply = <&vcc_1v8>;
vccio7-supply = <&vcc_3v3>;
};
修改后的效果图：
看这个料是贴的哪个 通过电阻切换的对应电压域电压
要和软件匹配上
RK原厂的buildroot刷机 荣品RK3566异常了
1、HDMI能够找到。没有显示。
2、电源域报警了。
原厂的电源域：

VCCIO2电平由硬件FLASH_VOL_SEL决定:
当VCCIo2供电是1.8V,则FLASH_VOL_SEL管脚必须保持为高电平;
当VCCIO2供电是3.3V,则FLASH_VOL_SEL管脚必须保持为低电平;
